EDR monitoring

We watch your endpoints on the platform you already run, triage the alerts, and guide containment when something is real.

Who this is for

  • You have an EDR platform but no one to run it

    The tool is only as good as the people watching it. You want alerts triaged and acted on, not left blinking on a console.

  • Endpoints are where your attacks begin

    Ransomware, lateral movement and privilege escalation all show up on the endpoint first. Watching there catches them early.

  • You want analysts who also understand attackers

    The people watching your endpoints are the same consultants who test networks offensively, so they know what an attack looks like from both sides.

We monitor your endpoint detection and response platform, triage and investigate the alerts, and guide containment, with threat hunting and tuning on top.

  • Continuous monitoring of your existing EDR platform
  • Alert triage and investigation by analysts, not automated forwarding
  • Containment guidance, and containment actions where agreed
  • Proactive threat hunting across the endpoint fleet
  • Detection and response mapped to the MITRE ATT&CK framework
  • Tuning to cut false positives and reduce alert fatigue
  • Escalation paths agreed with you, including out of hours
  • Monthly reporting on detections, hunts and tuning

How we test it

Endpoints are where most attacks become visible first. Ransomware, lateral movement, credential theft and privilege escalation all leave traces on the workstation or server before they reach anywhere else, which is why endpoint detection and response has become a core control. But an EDR platform is only as good as the people watching it, and a console of unread alerts protects no one. Aurian’s managed EDR monitoring puts analysts behind your existing platform: triaging, investigating, hunting and, where you grant the authority, containing.

The work is behavioural. Modern intrusions use the tools already on the machine, PowerShell, WMI, scheduled tasks, so what gives them away is behaviour: a document spawning an encoded script, a process deleting shadow copies, a service quietly installed for persistence. Our analysts investigate what the platform flags against detection mapped to the MITRE ATT&CK framework, decide quickly what is real, and act. Catching shadow-copy deletion and isolating the host within minutes, out of hours, is the difference between one reimaged machine and an organisation-wide ransomware outage.

Beyond responding to alerts, we hunt proactively for what no rule caught, tune the platform so false positives do not bury the real signal, and report each month on what we saw and did. The analysts are the same consultants who test networks offensively for our clients, so they recognise an attack because they run the same techniques themselves. EDR monitoring stands on its own, and it pairs naturally with SIEM monitoring, feeding endpoint depth into a picture that spans your whole environment.

  1. 01 Onboarding

    We connect to your EDR platform, learn your fleet and what normal looks like, and agree the escalation and containment authority with you.

  2. 02 Monitoring

    We watch detections continuously against rules mapped to MITRE ATT&CK, so endpoint activity is seen in the context of known attacker behaviour.

  3. 03 Investigation

    Analysts investigate what fires, decide what is real, and guide or take the containment action along the agreed path.

  4. 04 Hunting and tuning

    We hunt proactively for activity that no alert caught, tune the platform to cut noise, and report monthly.

What you receive

Every finding in an Aurian report looks like this: what we found, the evidence, what it means for you, and what to change.

Extreme AUR-2026-014 Sample finding, fictional environment

Ransomware precursor contained before encryption began

Affected asset
FIN-WS12, finance workstation
Rating
Extreme Likely 4 × Critical 6 = 24

Description

The EDR platform flagged a process spawning shadow-copy deletion, a common last step before ransomware encrypts. Analysts investigated within minutes, confirmed the behaviour matched a known ransomware playbook, and isolated the host on the agreed authority before any files were encrypted.

Evidence

[edr] 23:41 FIN-WS12: powershell -enc <b64>
      -> vssadmin.exe delete shadows /all /quiet
      -> parent: winword.exe (macro-enabled attachment)
[analyst] 23:47 behaviour matches ransomware precursor
[action]  23:49 host isolated; no encryption observed

Shadow-copy deletion spawned from a macro-enabled document was caught and the host isolated within eight minutes, before encryption.

Impact

Shadow-copy deletion is one of the last quiet steps before a ransomware attack encrypts and announces itself. Catching it and isolating the host within minutes, out of hours, is the difference between one reimaged workstation and an organisation-wide outage with a ransom demand.

Remediation

Reimage the isolated host and reset the user's credentials. Trace the macro-enabled attachment, block the sender and the pattern, and confirm application control and macro settings would stop a repeat. Hunt across the fleet for the same precursor on other hosts.

Common findings

What this kind of engagement typically surfaces, so you can recognise your own environment.

  • Ransomware precursors

    Shadow-copy deletion, mass file access and known tooling caught in the minutes before encryption, when isolation still helps.

  • Malicious macros and initial access

    Macro-enabled documents spawning scripts and downloads, the common first step of an intrusion.

  • Lateral movement

    Remote execution and credential use across hosts that reveal an attacker spreading from the first machine.

  • Living-off-the-land techniques

    Built-in tools such as PowerShell and WMI used for malicious ends, which signature tools miss and behaviour detection catches.

  • Persistence mechanisms

    Scheduled tasks, services and registry changes an attacker plants to survive a reboot, found by hunting.

  • Unmanaged and unprotected endpoints

    Machines missing the agent or excluded from policy, surfaced so coverage gaps are closed.

Frequently asked questions

Which EDR platforms do you support?

We work with your existing endpoint platform rather than requiring a change, and we tell you at onboarding whether it fits or what we would recommend.

Will you contain threats, or just tell us?

We triage and investigate, and we guide containment along the path we agree. Where you grant the authority, we take containment actions such as isolating a host directly, which out of hours can be the difference that matters. The authority stays yours to set.

How does this differ from SIEM monitoring?

EDR is deep visibility on the endpoints; SIEM correlates events across everything, including network, cloud and identity. They complement each other, and the EDR often feeds the SIEM. Many clients run both; some start with EDR because that is where attacks surface first.

Is it 24/7?

Alerts are triaged during business hours, and a consultant is on call for critical alerts outside them. We agree the escalation path and response expectations with you at onboarding, since out-of-hours cover is often where endpoint monitoring earns its place.

Do the same people who test also monitor?

Yes. The analysts watching your endpoints are Aurian consultants who also test offensively, so they recognise attacker behaviour because they use the same techniques in engagements.
